Elevate canned tuna with fresh herbs and melty cheddar in this Low FODMAP Herbed Tuna Melt Sandwich. This easy recipe uses just 8 ingredients and can be ready in under 20 minutes.


  • 2 low FODMAP English muffins, sliced in half (or 2 to 4 slices of low FODMAP bread, depending on recommended serving size) // notes 1 & 2
  • 1 (5-ounce) can tuna packed in olive oil, drained // note 3
  • ¼ cup mayonnaise, such as Hellmann’s 
  • 2 tablespoons finely chopped fresh chives (or 2 teaspoons dried chives)
  • 2 teaspoons finely chopped fresh flat-leaf parsley (or ½ teaspoon dried parsley)
  • 2 teaspoon finely chopped fresh basil leaves (or ½ teaspoon dried basil)
  • Sea salt and freshly cracked black pepper
  • 2 tablespoons shredded cheddar cheese // note 4
  • ½ medium Roma tomato, thinly sliced into 4 slices


  1. Move oven rack to 4-6 inches below broiler. Turn on the broiler.
  2. Toast the bottom halves of the English muffins (or 2 slices of bread). Transfer the toasted bread to an ungreased broiler-safe baking sheet or broiler pan.
  3. In a small bowl, mix tuna, mayonnaise, chives, parsley, and basil. Add salt and pepper, and adjust seasonings to taste.
  4. Stir in shredded cheddar cheese until well-mixed.
  5. Divide the tuna mixture evenly onto the toasted bread.
  6. Broil the open-faced tuna sandwiches for 5-7 minutes, or until the cheese melts and the tuna is warm. Cooking times are suggestions based on what works in my kitchen. To minimize the risk of burnt cheese, I recommend starting with less cooking time and adding time as needed. 
  7. Meanwhile, toast the remaining 2 English muffin halves (or 2 slices of bread).
  8. Remove the tuna melts from the oven. Top each half with 2 tomato slices and a just-toasted English muffin half. Cool slightly before enjoying warm.

Storage: Best enjoyed warm just after preparing.


Note 1: This recipe was tested with both Canyon Bakehouse Gluten-Free English Muffins and Food For Life Brown Rice English Muffins. Both products appeared to be made with low FODMAP ingredients at the time of publication. Individual tolerance may vary, and ingredients are always subject to change. 

Note 2: The Food For Life English muffin has a denser, chewier texture. My best recommendation for preparing the Food For Life English Muffins is to microwave the frozen muffins for 20-40 seconds until just thawed enough to slice in half. Toast and serve as soon as possible. These get chewier the longer they sit. 

Note 3: Water-packed canned tuna may be substituted. Some water-packed canned tuna products contain vegetable broth which may include higher FODMAP ingredients. Many people tolerate small amounts of FODMAPs. If concerned, choose tuna packed in oil or a water-packed canned tuna made without vegetable broth.

Note 4: Another low FODMAP cheese or non-dairy cheese substitute can be substituted. I like and use Daiya Cheddar-style Shreds.
